wow sangeeta...lots of thoughts...very deep...
what u say is right in your view...but I think everyone is watching this serial in different angles and that is why we all have different opinions.
Agree kids have to know the true emotions and should not supress...but KIDS...they learn what they see...if they can think deep like u and me...then they are no more kids...they have grown up...may be too early in their age and that is not just because of watching TV but also in the environment they are in.
Coming back to the serial..purab knew jassi loved armaan and he also knew that armaan is playing games with her. No one is that blind that they cannot know if some one is falling in love. Armaan knew that jassi is loving him and infact raj keeps telling that to armaan and make use of that...armaan never loved jassi. He just loved to defeat aryan and his ego which is making him do so many things like manipulating.
Purab inspite of knowing the truth is still in love with actual jassi...the way she is know...he loves her as a person and that is more respectful. He also never forced his decision. It was jassi who agrees and purab never officially proposes to her as far I know..
True first love is first...at the same time jassi can't be so dumb to chase armaan when she knows he is engaged and she respects elder suri and she does not want to say yes to armaan because she knows he is wrong. He goes out with mallika on a trip, stays in the same room and acts as though he is missing jassi...jassi may not say but she is not dumb to see what is happening. She knows what a flirt armaan is so she must be thinking that this is also armaan's infatuation and not really love.
